You shouldn't condition the same field twice. Again, it works in an OR scenario. This means if Condition 1 does not match and it's set to Show then it will Hide if the condition is not met. Next Condition 2 fires and if it's set to Show and the condition is not met then it will Hide. So if Condition 1 passed, but Condition 2 didn't then your field is hidden. The display (show, hide, required, non-required, etc..) always does the opposite if the condition is not met. With that in mind please adjust as necessary. Ideally in your situation you should use REGEX to match your textarea field using | to separate the 2 values so you're only using 1 Condition. REGEX value as follows.

I suggest maybe using a checkbox field or something of the sort to better match as you're matching a very select amount of text in a textarea field, which a user can provide whatever they want.
